Question

What must be true of a line whose slope is undefined?

Answer 1

Slope is also given as :
\[Slope = \tan(\theta)\]

Can you tell for what value of \(\theta), \(tan(\theta)\) will be Undefined??

Answer 2

if the slope of line is undefined this mean this line parallel to y-axis or make right angle with x-axis

Answer 3

The slope is undefined because division by 0 is undefined;

therefore what must be true of a line whose

slope is undefined is that the run = 0,
since
$$slope=\frac{rise}{run}$$

Answer 4

It would be a vertical line.
